Abstract

Calculation methods for microstrip line parameters by hand-calculator and/or by personal computer are needed for preliminary design purposes, and/or for quick evaluation purposes. In this research, the proposed algorithm, depicting the dynamic permittivity of the microstrip structure directly, leads to a convenient and modified Smith-chart representation that includes the frequency-dependent influence of the fringing field and the lossy characteristics, cohesively. Results based on the proposed model are compared with the available data in the literature in respect to a microstrip patch antenna in the frequency range of wireless personal area network (WPAN) applications such as Bluetooth and wireless local area network (WLAN). This model is compatible, for CAD efforts, with MATLAB, facilitating fast and user-friendly implementations.
